Embodiment Construction
[0020] The present invention is described in further detail below in conjunction with the embodiment that accompanying drawing provides.
[0021] see figure 1 As shown, a physiotherapy bed control system, the breathing acquisition module 2 includes a PVDF sensor belt 1 for detecting human chest vibration; the PVDF sensor belt 1 is made of PVDF piezoelectric film, and the PVDF sensor belt 1 can collect the human body The weak signal generated by chest movement during sleep breathing is amplified by the respiratory signal amplification and filtering module 22, and the unnecessary high frequency, low frequency, and power frequency signals are filtered, and then the respiratory frequency is analyzed by the respiratory signal processing module 21 .
[0022] The sound collection module 3 collects sound signals through the sound pickup module 33, filters unnecessary high frequency, low frequency, and power frequency signals through the signal amplification filter module 32, and then...
